The CMC Two Stage trigger features a non-adjustable flat trigger bow with a 4lb total pull weight that breaks like glass. It has almost no take-up and extremely short reset to make follow up shots fast and easy. The flat trigger gives you an increased surface area for your finger to contact and increases leverage when pulling the trigger. The hammer is lightened and uses a high-power Rocket Wire spring that ensures reliability with commercial and surplus ammunition. The high-power spring also results in minimal lock time, which is the time it takes for the hammer to fall and strike the primer, resulting in much more accurate shots. CMC Triggers have invested in a new production and tooling setup that incorporates advanced techniques that help to reduce manufacture time and cost while still providing you with a high quality, reliable trigger that is affordable.

Assembling an AR-15 for the most part is pretty simple; however, some aspects of the process can be frustrating such as installing the takedown detent and spring or trying to put the trigger together. CMC Triggers saw a need to improve on the AR15 trigger installation process and introduced their line of completely self-contained trigger groups. Each trigger is encased in 8620 alloy steel to protect the internal components from dirt and debris, carbon buildup, or anything else that might get into the lower receiver and can be installed in seconds. Just drop it in, install the Mil-Spec trigger pins and you are ready to go. They have a huge selection of triggers that are built for specific applications and preferences. This model is designed for target shooting, home defense, and hunting as it has a light, two stage trigger pull to improve accuracy without sacrificing reliability or safety. Install this fire control group today and experience a smooth trigger pull like never before.

With roots in aerospace manufacturing, CMC is perhaps best known as the producer of the original drop-in precision trigger for the AR-15/10 platform. CMC Triggers are dedicated to crafting the finest parts and accessories for law enforcement, military, and civilian use.

CMC trigger


Arrived on time and in good condition. I have not finished the build so I cannot comment on the trigger function. If it's like my first CMC trigger it will work well.

Love the CMC triggers


Can't say enough good stuff about the triggers from CMC. I have probably have about 20 of these triggers and each one has been great. There aren't many tings in life that are this consistent but these triggers are.

great product
